Phase retrieval algorithm applied to high-energy ultrafast lasers
Jikai Wang, Abdolnaser Ghazagh, Sonam Smitha Ravi +6
A standardized phase retrieval algorithm is presented and applied to an industry-grade high-energy ultrashort pulsed laser to uncover its spatial phase distribution. We describe in…
Dynamic focus shaping with mixed-aperture coherent beam combining
Maike Prossotowicz, Daniel Flamm, Andreas Heimes +5
A novel concept for dynamic focus shaping based on highly efficient coherent beam combining with microlens arrays (MLA) as combining element is presented. This concept allows to co…
Structured light for ultrafast laser micro- and nanoprocessing
Daniel Flamm, Daniel Günther Grossmann, Marc Sailer +9
The industrial maturity of ultrashort pulsed lasers has triggered the development of a plethora of material processing strategies. Recently, the combination of these remarkable tem…
Coherent beam combining with micro-lens arrays
Maike Prossotowicz, Andreas Heimes, Daniel Flamm +5
A novel concept for coherent beam combining is presented based on a simple setup with microlens arrays. These standard components are used in a proof-of-principle experiment for bo…
High-quality Tailored-edge Cleaving Using Aberration-corrected Bessel-like Beams
Michael Jenne, Daniel Flamm, Taofiq Ouaj +7
We report on the usage of ultrashort laser pulses in form of aberration-corrected Bessel-like beams for laser cutting of glass with bevels. Our approach foresees to incline the mat…
